This item was used by my mother and is currently out of battery. It has been stored for a long time. Only the top part, no necklace. There are some areas where the finish is peeling. It seems she used it with the blue sticker on the back still attached, lol. ★Since the battery is dead, I have not confirmed that it works, so please understand that it is a junk item. Model number: 1400-6970 Serial number: 130397
